To tape or glue

Matthewfalle

little tip as well when using tape:

put tape on wheel.

peel ff begining of tape and leave the "tongue" hanging over the edge.

pop tire on.

as you start to peel the backing off, just pull up the tire a couple of inches ahead of where you are peeling - means the backing won't catch and rip.

Matthewfalle

some people stick a pencil uber the tub and use that instead of fingers but i can't see the point tbh.

Matthewfalle

to tape a tub on should take - from blank, empty wheel to fitted and pumped up tub - about 5 minutes.

easiest thing ever.

In my experience, yes. Assuming you mean that if you are replacing a tyre, you can't usually use the existing tape..

Yes that's what I meant. I take it the old stuff just peels off easily?

I've only ever used Jantex, which is easy enough to remove. It either comes off with the tyre, or sticks to the rim, or sometimes a bit of both. The newest Jantex tapes with the plastic backing makes tyre fitting very easy - the old paper backings really were a test of patience..

Ok. Another question. If I get a puncture that a squirt of sealant won't fix and I have to fit a spare tub out on the road, assuming the tape comes off with the old tyre is it just a case of putting the new tyre on the rim and riding home slowly so it doesn't roll off?

Pretty much, yes. As mentioned somewhere upthread, a tub under pressure will not roll off the rim easily, even if there is no tape on it - but you certainly don't want to be railing around alpine hairpins at speed without tape on

Just a note on sealant and tubs - some use it, some don't. I prefer not to, on the basis that some tub repairers will not accept a tub for repair if there is sealant in the tube - too messy. In other words, if you have a tub with a puncture that sealant hasn't been able to fix, then sometimes the bin can be the only place for it. Sealant is also not necessarily reliable at high pressures. I have known of tubs that have had punctures, which sealant has fixed - but as soon as the tub is inflated to over 70psi (in one example), it started to blow out again and would only settle when it got below 70 again. 70psi might be fine for some - or useless for others...

just either carry a pre-taped spare tub or a roll of tape with you - its the size of a small roll of sellotape so you don't even notice it.

Matthewfalle

a properly rolled up spare tub doesn'take up much more space than an inner tube so no worries in carrying it.

Matthewfalle

the MFs aren't really too sure why people are so worried about tubs - they have seen far more problems with tubeless things full of sealant.

This is why I always use glue.

A friend's 'taped' wheel after his tubular rolled off today - he stayed upright... somehow.

Matthewfalle

and you are saying a taped tub caused a massive catastrophic wheel failure?

Matthewfalle

seriously?

No mention of the broken rim - that might have had something to do with it, perhaps. Either way, it's possible to roll a glued tub just as well as a taped tub - it all depends on how well it is fitted. Nothing can be read into that pic at all...

Don’t be daft (unless you use MTB inner tube). Try getting a folded 25mm tub close to the size of a standard road inner. If you can find one of those discontinued 22mm Tufo things then maybe, but that was just a get home emergency tub that was useless for normal riding.

Yep, not taped on securely, it rolled off and we think it got stuck between the wheel and the frame causing the wheel to buckle and snap at speed.

Accidents happen and not always as you expect them to, luckily nobody was hurt.

I'm not trying to be pedantic for the sake of it but are you absolutely certain that the tub rolled of and caused the wheel failure and not the other way around?

so he didn't tape his tub on properly and you are blaming the tape and not operator error?

result would have been the same if he hadn't glued it on properly

taping is fine - he just needs to do it properly.

I agree, user error for sure. I'd still rather have a tub glued on.

Definitely tub rolled off and caused the wheel failure; you could basically peel of the tub without any effort.

We then had a look at his front wheel, and I took that tubular off too, with no effort at all.

Presumably he did actually remove the backing from the tub tape before fitting..?

Yes, it was slightly sticky.

seems that he may not be too good at this.

can you keep an eye on him?

'slightly sticky' doesn't sound right. Tub tape is usually 'very' or 'extremely' sticky, ime. I'd be interested to know what tape it was...?

He'd just brought the wheels second hand with tubs fitted and made the criminal error of riding them without checking how securely they were fitted.

They are older wheels (circa 2010) with very little use, practically as new, the tubs may have been fitted years ago and not used... could the tape have dried up over time?

I think he got off lightly with a broken rim... if it had been the front one, on a fast descent...

ah - so old tape of unknown provenance and application or reason for being applied (the seller could just have popped some old taped tubs on to sell the wheels, told this to your mate who in the euphoria of new wheels ignored or forgot about it and went riding on tubs that weren't meant to be ridden on.

Matthewfalle

could have happened with glue.

Matthewfalle

so basically no reason at all to not use tape.

operator error.

Yep, could have. I guess it's a good lesson learned, and gotten away with... just damaged goods and pride.

exactly my friend, exactly.

I used to glue as I preferred the bond I got with it. But then I discovered this tape

https://road.cc/content/review/169313-e ... a-tub-tape

Really is a game changer for me

The downside of tape is that you have to get the rim surface perfectly clean to re tape. Also it’s tougher to remove and then re fit the same tub. The plus side is that the process is much quicker than gluing a tub.
